REMOVAL
CAUTION: Clamp only the narrow forged portion of
the yoke in the vise. Failure to heed caution may
result in damage.
(1) Remove axle shaft.
(2) Remove bearing cap retaining snap rings (Fig.
34).
NOTE: Saturate the bearing caps with penetrating
oil prior to removal.
(3) Place a socket (receiver) with an inside diame-
ter larger than the bearing cap against the yoke and
the perimeter of the bearing cap to be removed.
(4) Place a socket (driver) with an outside diame-
ter smaller than the bearing cap against the opposite
bearing cap.
(5) Position yoke with the sockets in a vise (Fig.
35).
(6) Tighten vise jaws, to force bearing cap into the
socket (receiver).
(7) Release vise jaws. Remove sockets and bearing
cap forced out of the yoke.
(8) Repeat above procedure for the remaining bear-

INSTALLATION
CAUTION: Keep cross and bearing cap straight dur-
ing installation. Failure to heed caution may result
in damage.
(1) Pack bearing caps 1/3 full of wheel bearing
lubricant (Fig. 36). Apply extreme pressure (EP), lith-
ium-base lubricant to aid in installation.
(2) Position cross in the yoke. Insert seals and
bearings, then tap bearing caps into the yoke bores
far enough to hold spider in position.
(3) Place socket (driver) against one bearing cap.
Position yoke with the socket in a vise.
(4) Tighten vise to force bearing caps into the
yoke. Force the caps enough to install retaining clips.
(5) Install bearing cap retaining clips.
(6) Install axle shaft.
PINION SEAL
REMOVAL
(1) With vehicle in neutral, position vehicle on
hoist.
(2) Remove brake rotors and calipers.
(3) Remove propeller shaft from the yoke.
(4) Rotate pinion gear three or four times.
(5) Record rotating torque of the pinion gear with
an inch pound torque wrench, for installation refer-
ence.
(6) Hold pinion yoke with Wrench 6958 and
remove pinion nut and washer.
(7) Remove pinion yoke with Remover C-452 and
Wrench C-3281 (Fig. 37).
(8) Remove seal with a pry tool or a slide hammer
mounted screw.
INSTALLATION
(1) Apply a light coating of gear lubricant on the
lip of pinion seal. Install seal with an appropriate
installer (Fig. 38).

(2) Install yoke on pinion gear with Installer
W-162-D, Cup 8109 and Holder 6958 (Fig. 39).
CAUTION: Do not exceed the minimum tightening
torque when installing the pinion yoke retaining nut
at this point. Failure to heed caution may result in
damage
(3) Install pinion washer and a new nut on the
pinion gear shaft.
NOTE: Tighten nut only enough to remove the shaft
end play.
(4) Tighten pinion nut to 217 N·m (160 ft. lbs.).
(5) Rotate pinion shaft using an inch pound torque
wrench. Rotating torque should be equal to the read-
ing recorded during removal, plus an additional 0.56
N·m (5 in. lbs.) (Fig. 40).
(6) If rotating torque is low, use Spanner 6958
(Fig. 41) to hold the pinion yoke and tighten pinion
shaft nut in 6.8 N·m (5 ft. lbs.) increments until
proper rotating torque is achieved.
(7) Install propeller shaft with reference marks
aligned.
(8) Install brake rotors and calipers.
